At the time of the cancellation - just 24 hours before the first show was to take place - Adele apologised to fans, saying that the show "just ain't ready", blaming it largely on Covid-19 delays.
With fans still reeling from the shock cancellation it is easy to understand why many were dismayed by Adele's joyful post about performing at the Brit Awards.
"What about all those people that have lost money because you cancelled at the last minute. Where is their performance?" a disgruntled fan commented, to which someone replied: "Yep. Exactly. Where is it? She could care less."
"What the actual f**k. So we just gonna forget about Vegas then?" another said.
"Coool…want to Venmo me now for the hundreds of dollars I lost because of your Vegas opening night cancellation? What a joke," seethed yet another.
Many are still in limbo, with flight costs going up in smoke and no word of when Adele will be rescheduling her Las Vegas dates.
"Adele, can you please give us an update on the Vegas shows," an upset fan asked. "I have two flights not giving me a refund and four tickets/people depending on an update."
The Weekends With Adele Vegas residency was set to begin on Friday, January 21 Las Vegas time and play two shows each weekend until April. With Adele set to earn almost $1 million per show, it was to be an easier alternative for an artist who famously does not enjoy touring and is now just a short plane ride away from Vegas in Los Angeles.
It's not the first time Adele has been forced to pull a big show at the last minute: in 2016, she was set to finish her Adele Live world tour with four massive shows at London's Wembley Arena. She had to cancel the final two of those shows at short notice because of damaged vocal cords, affecting almost 200,000 ticketholders.
